# List entity relationships

GET https://api.aventure.vc/v1/entities/{entityId}/relationships

Returns relationship rows touching the path entity. Defaults to renderable-only rows where isCurrent=true and isPrimary=true. Set includeNonRenderable=true to surface historic and non-primary curation rows; returned rows include id, isCurrent, and isPrimary so hidden-row cause is explicit. Use entities relationships row get to retrieve one row by id without an entity path.

Reference: https://docs.aventure.vc/api-reference/a-venture-api/entity-relationships/list-entity-relationships

## Authentication

- `X-Client-Secret` header (required) — Client secret for read-only service-to-service access (no writes)

## Request

### Path parameters

- `entityId` (string, required) — Canonical entity UUID

### Query parameters

- `type` (string, optional) — Optional EntityRelationshipType filter, one of: acceleratorParticipant, acquirer, affinity, calculated, competingProductService, competitor, customer, fundManagerFirm, parent, productService, serviceProvider, similarCompany, spinOffFrom, successor. Use entities relationships types for valid values.
- `includeNonRenderable` (boolean, optional, default: false) — Include historic or non-primary rows. Default false returns only rows where isCurrent=true and isPrimary=true.
- `cursor` (string, optional) — Opaque URL-safe cursor token from X-Next-Cursor. Reuse the same filters and sort.
- `transitive` (boolean, optional, default: false) — When true, returns direct curated competitors with each competitor's provider comparison signals (sells-to, pricing, ownership, funding, website) nested under its productService row. Competition is not transitively closed: A-B plus B-C surfaces B from A, never C. Only supported for type=competingProductService; the result is capped, so cursor and includeNonRenderable are not accepted alongside transitive=true.
- `page` (integer, optional, default: 0) — Zero-based page index (0..N)
- `size` (integer, optional, default: 20) — The size of the page to be returned
- `sort` (list of string, optional) — Sorting criteria in the format: property,(asc|desc). Default sort order is ascending. Multiple sort criteria are supported.

## Response

### 200

OK

- `content` (list of object, optional)
  - `entity` (object, required) — Joined entity on the other side of this relationship — read-only display projection. Writes identify both sides only via the flat sourceEntityId and targetEntityId UUIDs, never a nested entity object.
    - `id` (string, required) — Unique entity identifier
    - `image` (object, required) — Logo and monogram image metadata
      - `isMonogram` (boolean, required) — Whether entity image monogram
      - `logo` (string, optional, nullable)
      - `logoSquare` (string, optional, nullable)
    - `nameAlias` (list of object, required) — All names this entity has been known by — current alternates, DBAs, former names, and rebrand-source identities. Naming history (e.g. `Metaphor Systems` for the current `Exa` entity) lives here; never as a separate relationship type or `formerName` field.
      - `name` (string, required) — Alternate name text
      - `displayable` (boolean, optional, nullable) — Show this alias in public name displays.
      - `type` (enum, optional, nullable) — Alias type classification
        - Allowed values: `alternativeDba`, `relatedLegal`
    - `nameBrand` (string, required) — Resolved display brand name
    - `slug` (string, required) — URL-safe identifier
    - `createdAt` (datetime, optional, nullable) — Record creation timestamp
    - `defaultCurrency` (string, optional, nullable) — Default currency code (ISO 4217)
    - `foundedYear` (integer, optional, nullable) — Year the entity was founded
    - `lastModifiedAt` (datetime, optional, nullable) — Provenance-grounded last-modified watermark (schema.org dateModified). Advances only when a real, consumer-meaningful data point changes via a recorded provenance event — never on timestamp-only writes, migrations, or index refreshes. Pairs with createdAt (dateCreated) and grounds the sitemap lastmod.
    - `nameLegal` (string, optional, nullable) — Registered legal name
    - `operatingStatus` (string, optional, nullable) — Current operating status. Use Acquired Subsidiary when the entity was acquired and still operates; use Acquired only when it is terminal, folded, or closed.
    - `publicId` (string, optional, nullable) — Stable, immutable public handle (e.g. `eV1StGXR8Z5a`). Never changes once assigned, unlike the slug. Null on projections that do not select it and on rows still awaiting handle backfill.
    - `publicUrl` (string, optional, nullable) — Absolute public profile URL on the aVenture front-end, e.g. `https://aventure.vc/non-profits/{slug}`, derived from the typeRecord's canonical route family. Null when the route needs relationship context or the record has no direct public SSR route (Business Line, Organization, Product, Service, or a non-public slug). EntityDetail.publicUrl resolves Business Line parent context. Product/Service pages are provider-nested: compose the provider entity's publicUrl + `/products-services/` + this record's slug, or consume the sitemap-urls slot paths, which already emit the composed child routes.
    - `sitemap` (object, optional, nullable) — Sub-route eligibility, populated by the sitemap projection. Null on non-sitemap reads to keep thin payloads compact.
      - `hasAnalysis` (boolean, required) — Whether the profile Analysis sub-route should be emitted.
      - `hasEmployees` (boolean, required) — Whether the profile Employees sub-route should be emitted.
      - `hasFundraising` (boolean, required) — Whether the profile Fundraising sub-route should be emitted.
      - `hasNews` (boolean, required) — Whether the profile News sub-route should be emitted.
      - `productServiceSlug` (list of string, required) — Slugs of related Product/Service entities that should each get their own `/companies/<slug>/products-services/<productSlug>` URL, capped at `MAX_PRODUCT_SERVICE_SLUGS` server-side. Derived from current `productService` relationships in either stored direction; the entity relationships resource is the authoritative, read-your-writes view of those joins.
      - `hasAcquisitions` (boolean, optional, default: false) — Whether `/companies/<slug>/acquisitions` should be emitted. True only when an acquisition relationship exists AND both the acquired and acquirer entities are publicly visible. A confirmed acquisition relationship row with this flag `false` (or with `entities acquisitions list` returning zero rows) means a counterpart entity is still hidden -- publish it -- it is a visibility gate, not list lag.
    - `typeRecord` (enum, optional, nullable) — Entity type classification
      - Allowed values: `Company`, `Investment Firm`, `Fund`, `Nonprofit`, `Government`, `Organization`, `Business Line`, `Product`, `Service`
    - `updatedAt` (datetime, optional, nullable) — Last modification timestamp
  - `relationship` (list of object, required) — Nested relationships for the joined entity
  - `relationshipType` (string, required) — Canonical relationship type, one of: acceleratorParticipant, acquirer, affinity, calculated, competingProductService, competitor, customer, fundManagerFirm, parent, productService, serviceProvider, similarCompany, spinOffFrom, successor. Similarity endpoint rows use stored relationship types when a curation row exists and calculated when the row comes from semantic/vector similarity.
  - `asOf` (date, optional, nullable) — Effective date for this relationship when known
  - `comparisonSignals` (object, optional, nullable) — Competitive comparison signals for the joined entity when it is a product/service provider — sells-to, pricing model, ownership, funding, and website. Null for every other joined entity. Lets comparison surfaces render provider columns without a second per-provider fetch.
    - `ownership` (list of string, required) — Provider ownership structure (current typeOwnership tags)
    - `pricingModel` (list of string, required) — Provider pricing/revenue model (current typeRevenue tags)
    - `sellsTo` (list of string, required) — Customer types the provider sells to (current typeCustomer tags)
    - `fundingStage` (enum, optional, nullable) — Latest funding stage when known
      - Allowed values: `Angel`, `Pre-Seed`, `Seed`, `Series A`, `Series B`, `Series C`, `Series D`, `Series E`, `Series F`, `Series G`, `Series H`, `Series I`, `Series J`, `Series K`, `Series L`, `Series M`, `Series N`, `Series O`, `Series P`, `Series Q`, `Series R`, `Series S`, `Series T`, `Series U`, `Series V`, `Series W`, `Series X`, `Series Y`, `Series Z`, `Investment Firm`, `Fund`, `Nonprofit`, `Government`, `Public`, `Acquired`, `Acquired Subsidiary`
    - `totalRaised` (double, optional, nullable) — Total capital raised when known
    - `website` (string, optional, nullable) — Provider website URL when known
  - `createdAt` (datetime, optional, nullable)
  - `detail` (string, optional, nullable) — Relationship-specific detail. acceleratorParticipant rows use `batch=<label>`, or `program=<name>; batch=<label>` only for a distinct sub-program. program= never repeats the accelerator name or the batch, and batch= never contains the accelerator name — the row already points to the accelerator entity.
  - `id` (integer, optional, nullable) — Integer entity_relationship.id row id, not an entity UUID
  - `isCurrent` (boolean, optional, nullable) — Current-state curation flag for this relationship row. Default relationship reads return only rows where isCurrent=true and isPrimary=true.
  - `isPrimary` (boolean, optional, nullable) — Primary/renderable curation flag for this relationship row. isCurrent=false or isPrimary=false hides the row from default relationship reads.
  - `source` (string, optional, nullable) — Source URL or compact source label copied to the relationship row
  - `sourceEntityId` (string, optional, nullable) — Canonical source entity UUID stored on the relationship row. Compare with the requested entity id and `/v1/entities/relationships/types` sourceRole/targetRole to orient directional relationships such as parent.
  - `targetEntityId` (string, optional, nullable) — Canonical target entity UUID stored on the relationship row. Compare with the requested entity id and `/v1/entities/relationships/types` sourceRole/targetRole to orient directional relationships such as parent.
  - `updatedAt` (datetime, optional, nullable)
- `empty` (boolean, optional)
- `first` (boolean, optional)
- `last` (boolean, optional)
- `number` (integer, optional)
- `numberOfElements` (integer, optional)
- `pageable` (object, optional)
  - `offset` (long, optional)
  - `pageNumber` (integer, optional)
  - `pageSize` (integer, optional)
  - `paged` (boolean, optional)
  - `sort` (object, optional)
    - `empty` (boolean, optional)
    - `sorted` (boolean, optional)
    - `unsorted` (boolean, optional)
  - `unpaged` (boolean, optional)
- `size` (integer, optional)
- `sort` (object, optional)
  - `empty` (boolean, optional)
  - `sorted` (boolean, optional)
  - `unsorted` (boolean, optional)
- `totalElements` (long, optional)
- `totalPages` (integer, optional)
